I poked around there for a while, and my takeaway was "sub-par" all around, which might be the reason for it's relative obscurity? The thing is, I can't tell to what extent it's the tech, and to what extent it's just "very uninteresting source material."

Like, there's a whole lot of "classic song done by presently popular rapper," and I'll be the first to insist that there is nearly nothing vocally interesting at all coming from todays popular hip-hop artists (and I say this as an extreme long-time hip-hop aficionado)
